Field CBR Testing Machine – On-Site Soil Strength & Subgrade Evaluation

The Field CBR Testing Machine is a rugged and portable system designed to determine the California Bearing Ratio (CBR) of soil directly at field locations. Ideal for highway construction, embankment development, railway track beds, and pavement foundation engineering, this equipment enables engineers to assess subgrade load-bearing capacity without transporting samples to a laboratory.

Built with a sturdy mechanical loading system and accurate proving ring setup, the field CBR apparatus delivers reliable penetration readings even in remote testing environments. Easy to assemble, transport, and operate, it ensures fast decision-making for earthwork and compaction quality control at construction sites.

Whether you’re validating compaction results or approving site soil for structural load applications, the Field CBR Testing Machine provides dependable data to support safe and efficient infrastructure development.
